Scientists at Arizona State University have made a groundbreaking discovery about the movement of water within the Earth’s crust and core. According to a recent study, water slowly seeps from the Earth’s surface to the inner core, leading to the formation of a new layer between the outer core and the Earth’s outer mantle.
The process, although slow, has been ongoing for billions of years, creating a new layer that is “a few hundred kilometers” thick. This discovery challenges previous assumptions about the physical exchange between the Earth’s core and mantle, indicating a much more dynamic interaction.
Dr. Dan Shim, co-author of the study, explained, “For many years, the physical exchange between the Earth’s core and mantle was thought to be small. However, our recent experiments at high pressure reveal a different story.” The water that reaches the core-mantle boundary triggers a chemical reaction, forming silica in the core.
This discovery has significant implications for our understanding of the Earth’s internal processes and the global water cycle. It indicates a more extensive water cycle than previously recognized and has the potential to impact geochemical cycles linking the surface water cycle to the deep mineral core.
The findings from this study provide valuable insights into the Earth’s complex and dynamic systems, shedding light on the interconnected processes that shape our planet. The link to the source of this news article can be found here:
